...Máté Szűcs; György Krallics; John G. Lenard The flat rolling process is initiated when the frictional forces draw the strip to be rolled into the roll gap. These forces depend on the coefficient of friction, knowledge of which is essential to understand, describe, and analyze the process. Several...

... on the worn scars, which protected the tribo-surfaces and subsided the wear. The reduced graphene oxide (rGO) with the interlamellar distance of 0.35 nm in the (002) plane provided minimum resistance to shear and exhibited maximum reduction in coefficient of friction (COF) for the paraffin grease...

... by the advanced stir-casting method. Besides measurements of density, porosity, and Vickers hardness, in-depth characterizations of microstructures were performed. Specific wear-rate (SWR), coefficient of friction (COF), and abraded surface roughness (SR) of developed materials were measured under two-body...

... may compromise the friction. This paper reports on wetting, dry friction, and roughness properties of TiO 2 coated (hydrophilic) and polymethyl hydrogen siloxane (PMHS) coated (hydrophobic) self-cleaning ceramic tiles. The coefficient of friction values of the tile–rubber interface do not change...

.... With an increasing load and contact area of interacting bodies, the coefficient of friction first drops sharply with an increasing normal load and then begins to grow. We have found out that the adhesion component of friction contributes to the friction coefficient at small loads. We have shown that the hardness...
